SYNOPSIS OF ACTIVITY
--------------------

             Solar activity was very low. Today's activity consisted
       of a few, low level B-class flares. Region 978 (S07E01) is the only
       sunspot region on the disk and is a 240 millionths eai beta-gamma
       group. The group has been relatively stable during the past 24
       hours. There appears to be a new region rotating around east limb
       near N28.

            Solar activity forecast:  solar activity is expected to be very
       low to low. There is a fair chance for an isolated C-class event
       sometime during the next three days (12-14 december).

            The geomagnetic field was mostly unsettled although there was an
       active period from 10/2100Z-11/0000Z. Solar wind observations from
       ace show the onset of a co-rotating interaction region late
       yesterday, followed by the onset of a high speed stream around
       11/0000Z. Peak solar wind speeds were around 650 km/s. Nonetheless
       the solar wind magnetic field has been relatively weak since
       11/0130Z. The solar wind speed is currently declining slowly with
       values around 550 km/s at forecast issue time.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be predominantly unsettled with a chance for an isolated
       active period for 12 december. Conditions should be predominantly
       quiet for 13-14 december.
